Detailed Description

For further understanding of the features and technical means of the present invention, as well as the specific objects and functions attained by the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.

In order to solve the technical problem of how to further improve the tensile property of the cable by changing the structure, as shown in fig. 1-2 and fig. 7-8:

an insulated cable structure with good tensile property comprises an electric wire 1, a second tensile mechanism 4 and a copper wire mesh grid 5; the H also comprises a supporting mechanism 2 and a first tensile mechanism 3; the second tensile mechanism 4 includes a first insulating layer 4a, a second insulating layer 4b, and a triangle 4 c; the first tensile mechanism 3 is of a circular structure, and the first tensile mechanism 3 is arranged on two sides of the electric wire 1; the supporting mechanism 2 is fixedly arranged on the first tensile mechanism 3; the first insulating layer 4a is fixedly arranged at one end of the first tensile mechanism 3 far away from the supporting mechanism 2 around the axis of the first tensile mechanism 3; the second insulating layer 4b is arranged outside the first insulating layer 4a around the axis of the first tensile mechanism 3, and a gap is reserved between the first insulating layer 4a and the second insulating layer 4 b; the triangular pieces 4c are uniformly arranged in the gap along the longitudinal direction of the first insulating layer 4 a.

Based on the above-mentioned embodiment, this application electric wire 1 sets up in first tensile mechanism 3, and electric wire 1 is provided with many, sets up like this and can guarantee signal transmission's stability, and electric wire 1 winds on first tensile mechanism 3 around the axis spiral of first tensile mechanism 3. A second tension mechanism 4 is provided outside the first tension mechanism 3. A through hole is reserved between the first tensile mechanism 3 between the electric wire 1 and the second tensile mechanism 4, and a copper wire weaving net is arranged on the through hole. The material of the triangle 4c is preferably a flexible insulating material. The triangular piece 4c is formed by rotating a triangular structure around the first tensile mechanism 3, the triangular piece 4c is cut along the radial direction of the triangular piece 4c, and the obtained section is of the triangular structure uniformly distributed along the length direction of the triangular piece 4 c. By using the triangular stability principle, a certain strength can be provided for the first tensile mechanism 3. The first insulating layer 4a and the second insulating layer 4b are also tensile insulating materials, so that the tensile strength is further improved by combining the triangular structure of the triangular piece 4c on the basis of the material strength of the first insulating layer 4a and the second insulating layer 4 b. The triangular structure on the triangle 4c is not filled with material. This is because the storage of the cables by cable reels is usually done by personnel when transporting the cables. The cable needs to be wound on the cable drum, and if the triangular structure in the triangular piece 4c is filled with the filler, the bending performance of the cable can be greatly reduced, so that the cable is inconvenient to be wound on the cable drum, and the transportation of the cable is affected. The supporting mechanism 2 is arranged because no filler is filled in the triangular piece 4c, so if the supporting mechanism 2 is not arranged, when a cable is erected, the cable starts to fall down due to the gravity of the cable because the length of the cable has a certain length, so that the triangular piece 4c which is not filled with the filler and is originally convenient for bending the cable can aggravate the falling process of the cable and increase the burden of the first insulating layer 4a and the second insulating layer 4b, and the first insulating layer 4a and the second insulating layer 4b can be broken due to material fatigue in the past. At the same time, the tensile structure of the triangle 4c is broken, thereby reducing the tensile performance of the first tensile mechanism 3. After the supporting mechanism 2 is arranged, the cable can be sectionally supported by the supporting mechanism 2, so that the cable is not easy to fall. The tensile capacity of the triangular piece 4c in the length direction of the cable is guaranteed, and the service life of the first insulating layer 4a and the service life of the second insulating layer 4b are prolonged. So just realized on the basis that is provided with tensile material, through the change to the structure, further strengthened the tensile property of cable to electric wire 1 has been protected and has been protected from the injury.

Further, in order to solve the technical problem how the first tensile mechanism 3 enhances the tensile performance of the cable, as shown in fig. 2:

the first tensile mechanism 3 includes a main wire 3a and a sub-wire 3 b; the main wire 3a is provided inside the electric wire 1 in the axial extending direction of the first insulating layer 4 a; the secondary wires 3b are fixedly arranged on the support structure uniformly around the axis of the first insulating layer 4 a.

Based on the above embodiments, the main wire 3a is preferably a steel wire, the sub-wire 3b is preferably a steel wire, the diameter of the main wire 3a needs to be larger than that of the sub-wire 3b, the main wire 3a is a circular column structure, and the electric wire 1 is spirally wound around the axis of the main wire 3a on the outer side wall of the main wire 3 a. The longitudinal direction of the sub-line 3b is parallel to the longitudinal direction of the main line 3 a. The supporting mechanisms 2 are fixedly arranged on the main line 3a around the axis of the main line 3a, and the supporting mechanisms 2 are uniformly arranged along the length direction of the main line 3 a. Because the supporting mechanism 2 is arranged on the first tensile mechanism 3 in a segmented manner, the auxiliary wire 3b is fixedly arranged between the adjacent supporting mechanisms 2, and the auxiliary wire 3b is preferably arranged on one side of the supporting mechanism 2 away from the main wire 3a, so that enough space can be provided for the electric wire 1 wound on the main wire 3a, and meanwhile, a frame structure can be formed between the auxiliary wire 3b and the main wire 3a, and the situation that the force borne by the cable is completely concentrated at one point when the cable is stressed, so that the main wire 3a and the auxiliary wire 3b are damaged is avoided. Thus, the technical requirement for further enhancing the tensile property of the cable is met, and the problems are solved.

Further, in order to solve the technical problem of how to ensure that the electric wire 1 located therein is not damaged when the cable is stretched, as shown in fig. 3:

the first tensile mechanism 3 further includes a void 3 c; the space 3c is provided between the wires 1.

Based on the above embodiment, the gap 3c of the present application is not set too large, so as not to cause unnecessary waste. Since the electric wire 1 is spirally wound on the main wire 3 a. Therefore, the electric wire 1 can be displaced due to the deformation of the first tensile mechanism 3 and the second tensile mechanism 4 during stretching, and the gap 3c between the electric wires 1 is arranged at the moment, so that a space can be provided for the movement of the electric wire 1, and certain moving spaciousness between the electric wires 1 is ensured, so that the electric wires 1 positioned in the electric wire 1 can not be damaged due to mutual friction when the cable is stretched, and the problem is solved.

Further, in order to solve the technical problem of how the supporting mechanism 2 supports the cable, as shown in fig. 6:

the support mechanism 2 comprises a support rod 2a and a support ring 2 b; the support rods 2a are uniformly and fixedly arranged on the main wire 3a around the axis of the main wire 3 a; the support ring 2b is fixedly arranged at one end of the support rod 2a far away from the main line 3 a.

Based on the above embodiments, one end of the support ring 2b away from the support rod 2a is connected to the first insulating layer 4a, the support rods 2a are fixedly arranged on the main wire 3a along the radial direction of the main wire 3a, the support rings 2b are in one-to-one correspondence with the support rods 2a, the support rings 2b are arranged on the support rods 2a along the axial extension direction of the main wire 3a, the distance between adjacent support rods 2a is not too short, otherwise the bending of the cable is affected; the distance between the adjacent support rods 2a is not suitable for the process, otherwise, the support effect cannot be achieved, so that the support function of the support mechanism 2 is realized, and the problem is solved.

Further, in order to solve the technical problem of how to prevent the cable from entering water during use, as shown in fig. 2:

the waterproof jacket 6 is fixedly arranged on the periphery of the second insulating layer 4b around the axis of the first tensile mechanism 3.

Based on the above embodiment, the material of the waterproof jacket 6 of the present application is preferably PVC material, so that when it rains or encounters water, the waterproof jacket 6 blocks the rain, so that the external water does not affect the wires 1 in the cable, thereby solving the above problems.

Further, in order to solve the technical problem of how to prevent the cable from being damaged due to friction during use, as shown in fig. 1:

the wear-resistant layer 7 is fixedly arranged on the periphery of the waterproof jacket 6 around the axis of the first tensile mechanism 3.

Based on the above embodiment, the wear-resistant layer 7 of the present application can be formed by coating wear-resistant paint or directly coating wear-resistant material on the outer layer of the waterproof jacket 6, thereby solving the above problems.

The above examples, which are intended to represent only one or more embodiments of the present invention, are described in greater detail and with greater particularity, and are not to be construed as limiting the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
